FuseBox RTA105030C RCBO 50A 30mA 10kA

The FuseBox RTA105030C is a high-performance 50A Type A RCBO (Residual Current Breaker with Overcurrent protection) designed to provide combined protection against overloads, short circuits, and earth leakage faults in modern electrical distribution systems.

Rated at 50A with a 30mA residual current sensitivity, the device features a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents such as lighting circuits, small motors, and general power distribution. It also provides a 10kA short-circuit breaking capacity, ensuring reliable fault interruption under high fault conditions.

The RTA105030C is a 1P+N switched neutral RCBO, meaning it disconnects both line and neutral conductors during a fault, improving safety and isolation. Its Type A sensitivity allows detection of both AC and pulsating DC residual currents, making it suitable for modern installations with electronic loads and appliances.

Designed for use in FuseBox consumer units and distribution boards, the device is DIN rail mounted and compact (1 module wide), helping to save space while maintaining full circuit protection. It complies with IEC/EN 61009-1 standards, ensuring adherence to modern electrical safety regulations.
